Oil Free ----Totally Oil Free:
Oil free water lubrication screw air compressor is a kind of compressor that provides clean, pollution-free, 100% oil free screw air compressor, its zero emission can protect the environment efficiently.
Water ---- Lubrication, Sealing and Cooling:
Ideal isothermal compression High efficiency (large air delivery)
Low temperature compression No need the intercooler and after cooler
Low rotation speed Low noise, low vibration and no need the overdrive gear
Low viscosity of lubrication water Easy to be separated with the air
All stainless steel pipe : Simple ,non-corrosive,non-polluting,high reliablity
Single Stage Compression ,High Efficiency ,and Energy Saving ,and Easy Maintenance: Single stage compression makes the structure easy.
Compression efficiency is higher than the two stage dry air compressor.
Less consumable parts, easy to be disassembled, reduce the maintenance cost and time greatly.
